Current forecast guidance from the Finnish Meteorological Institute and ECMWF ensemble runs points to an overnight low in Helsinki on September 21 near 8–10 °C, with trader consensus split between the sub-5 °C and 9 °C buckets reflecting model spread on cloud cover and boundary-layer winds. A northwest wind shift after frontal passage is expected to enhance radiative cooling under partly clear skies, while residual moisture could limit the drop; historical September minima average near 7–9 °C. Key resolution hinges on the precise timing of clearing and wind speeds overnight, with updated model runs and FMI nowcasts likely to refine probabilities before the minimum is recorded.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 21 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Current forecast guidance from the Finnish Meteorological Institute and ECMWF ensemble runs points to an overnight low in Helsinki on September 21 near 8–10 °C, with trader consensus split between the sub-5 °C and 9 °C buckets reflecting model spread on cloud cover and boundary-layer winds.
